Hello:
I am looking to make a circuit to blend two stereo signals into one stereo output.
Originally I had wanted to do this as a strictly passive endeavor. But I realized that I would need to utilize a quad-gang potentiometer and would probably see some signal loss due to impedance issues.
My idea now is to use two TL072 to buffer both sets of L/R signals coming in so that they are both at unity gain.
Then blend those signals with a dual gang potentiometer set as a variable resistor.
And then have the wipers of the potentiometer output through a third TL072 buffering the output.
Will this work? If so is it an ill advised method?
Thanks
James
